I had one upper wisdom tooth that never came in, (or else had it yanked and don't remember it) the other upper came out about 10 years ago, one lower one came out 2-3 years ago, and the last one is still in place.
My wife on the other hand, had 3 full sets of wisdom teeth pulled...they'd pull a set, within about 3 years, they were coming back...I'd tell her she must be related to the sharks...
